Question

William is developing the model shown below to illustrate the process of photosynthesis. He plans to use the model to explain how photosynthesis transforms both energy and matter.

In a key or legend for the model, how should William describe the roles of NADPH and ATP in the light-independent reactions?
A.
providing the oxygen for sugar molecules
B.
providing the carbon for sugar molecules
C.
absorbing the energy of light and transferring it to electrons
D.
supplying the energy necessary to assemble sugar molecules

Answer 1

In the key or legend for the model, William should describe the roles of NADPH and ATP in the light-independent reactions as 1) absorbing the energy of light and transferring it to electrons, and 2) supplying the energy necessary to assemble sugar molecules.

Step-by-step explanation:

In the key or legend for the model, William should describe the roles of NADPH and ATP in the light-independent reactions as:

C. absorbing the energy of light and transferring it to electrons

D. supplying the energy necessary to assemble sugar molecules

NADPH and ATP are both energy carriers that are produced in the light-dependent reactions. NADPH absorbs the energy of light and transfers it to electrons, while ATP supplies the energy necessary to assemble sugar molecules in the light-independent reactions.
